murraysovereign Posted December 9, 2007 Share Posted December 9, 2007 I'm curious what MEC is going to sell for rainwear now. Ventile cotton anoraks? Waxed cotton? For the moment they're still selling Gore-Tex and such. If they had been selling some sort of Lexan rainwear, they would have pulled it, but I've never heard of anyone making Lexan clothing. However, the PTFE that most waterproof/breathables (like Gore-Tex) are based on is itself coming under increased scrutiny, particularly because of its bio-accumulative properties. So, yes, Gore-Tex could be next, along with all kinds of other technical fabrics. After that it will be things like flourinated ski waxes, and who-knows-what-all-else.

TREETOAD Posted December 10, 2007 Share Posted December 10, 2007 I've used aluminium for years but I can't remember why. Quote Link to comment Share on other sites More sharing options...
catbirdseat Posted December 10, 2007 Share Posted December 10, 2007 avi, when u get to it, you'd best correct your subject line. MEC took all their POLYCARBONATE products (a.k.a. Lexan) off their shelves. there are plenty of other plastics available, including Nalgene PTFE waterbottles. cheers, I didn't know theyb made PTFE waterbottles. I imagine that they'd be expensive and heavy. Are they? They should be quite inert, I should think. I think Don meant HDPE - those are the softer, nearly opaque white bottles that Nalgene makes, and as far as anyone knows so far, they're perfectly safe. PTFE is commonly known as teflon, as used in non-stick frying pans and waterproof-breathable laminates, and, apparently, as a protective coating for certain politicians. I happen to know that one can buy PTFE bottles. They are made for laboratory use. They are expensive. I have one. It's kind of heavy. HDPE is pretty safe as far as I know but it smells funny.

ketch Posted December 10, 2007 Share Posted December 10, 2007 Heat may increase the amount of BPA leaching out of the polycarbonate bottles. Does that mean that when I use my REI lexan Tiki head pee bottle that it will increase the risk of estogen in my urine. Quote Link to comment Share on other sites More sharing options...
dmuja Posted December 10, 2007 Share Posted December 10, 2007 Re: PTFE "Teflon" If you overheat PTFE the gases are toxic. Also, Perfluorooctanic acid "PFOA" is used in making teflon for pans and is a "potential carcinogen." And, research from Johns Hopkins Hospital has shown that PFOA is in the umbilical cord blood of 99 percent of newborn babies. Of coarse its just my opine, but Id venture to say that there is no such thing as a plastic container of any kind that does not leach something into what it is containing. Thats not a reason to panic, just cause for informing oneself and thus making informed choices. How often would you really require the use of a Lexan bottle anyway? Maybe glass is a good substitute for mixing/storing things in around the home. http://www.cbsnews.com/stories/2006/02/07/earlyshow/health/health_news/main1289747.shtml http://www.townsendletter.com/June2006/healthrisk0606.htm Quote Link to comment Share on other sites More sharing options...
Dechristo Posted December 10, 2007 Share Posted December 10, 2007 Now I'm trying to figure out what to do with several cases of Nalgene... The new dedicated pee bottles. Quote Link to comment Share on other sites More sharing options...
MarkMcJizzy Posted December 10, 2007 Share Posted December 10, 2007 I happen to know that one can buy PTFE bottles. They are made for laboratory use. They are expensive. I have one. It's kind of heavy. HDPE is pretty safe as far as I know but it smells funny. We all thank you for that critical and fascinating update. Kind of elitist too "They are expensive", meaning us peons can't afford one. "I have one" - oh, your so cool. "It's kind of heavy" - oh, your so tough. I know what else smells funny.

ClimbingPanther Posted December 10, 2007 Share Posted December 10, 2007 so the bottles appear to have the same pattern of adversely affected population as alcohol (excluding abuse)... pregnant women. we still have alcohol, why kill the nalgene? MEC, you're dumb. Quote Link to comment Share on other sites More sharing options...
cycling_mike Posted December 11, 2007 Share Posted December 11, 2007 Hey, maybe if drinking out of polycarbonate bottles got you drunk you'd have a point. As it is, drinking alcohol is fun while carrying water in a nalgene (as opposed to some other container) is not. I for one see no reason to expose myself to toxins, or potential toxins, that aren't fun. Quote Link to comment Share on other sites More sharing options...
max Posted April 19, 2008 Share Posted April 19, 2008 Running water is ruining our lives. Did you mean to so "Ruining water is running our lives"? Quote Link to comment Share on other sites More sharing options...
jordansahls Posted April 19, 2008 Share Posted April 19, 2008 (edited) They just need to stop using BPA. Correct me if im wrong, but isnt it a plasticizer? So it lowers the processing temperature of the polycarbonate material that the are using, thereby lowering the manufacturing costs. Isn't it also questionable if the amount of BPA leeching into the water is at a harmful concentration? Still, it seems like most anything can be cancerous or deadly these days.
